PopularMusicPlayerEcoutePulledFromAppStoreAfterUsingAPrivateAPI

Powerful third-party music player Ecoute has been pulled from the App Store after using a private API.
Developer PixiApps announced the news on Twitter earlier today. The app disappeared from the store on Saturday.

Got some news from Apple, like we thought, we've been removed because of the use of a private API.

According to Twitter posts from the Ecoute account, the API in question allowed users to edit the music queue even if they started listening from the stock app. That was apparently a big no-no in Apple’s eyes.
The queue manager was added into the app in version 2.1, which arrived in early January.
But the good news is that the next update will remove the ability to edit the music queue unless a user starts directly from Ecoute.
There’s no word on when the app will reappear, but hopefully PixiApps can get the issue taken care of quickly.
The app originally landed back in 2012. Just before the end of the year, it made the move up to version 2.0. That brought an iOS 7-style interface and improved Last.fm song "scrobbling."
We’ll let you know when Ecoute returns to the App Store.
